**Answer:**

2.) 4x +7 > -5

**Step-by-step explanation:**

because

4x +7 > -5

4x > -5-7

4x > -12

x > -3

hope it will help you

plz follow me

**1.** since the equations equal each other

2x+19=x+7

-x -x

x+19=7

-19 -19

**x= -12**

sub into y= x+7

y= -12+7

**y= -5**

**2.** x+2y=-7

<span>x+y+23=0

i don't know what the second equation is equal to, i'll assume 0

2y=x-7

y=1/2x-7/2

sub this into x+y+23=0

x+1/2x-7/2+23=0

3/2x+39/2=0

-39/2 -39/2

3/2x= -39/2

x=-39/2 / 3/2

**x= -13**

sub into y=1/2x-7/2

y=1/2(-13)-7/2

**y= -10**

**3.** </span>x+5y=2

<span>x=-4y+5

</span>sub x=-4y+5 into x+5y=2

-4y+5+5y=2

y+5=2

-5 -5

**y= -3**

sub y =-3 into x =-4y+5

x=-4(-3)+5

**x= 17**

**4.** 3x+y=9

<span>y=-5x+9

</span>sub -5x+9 into 3x+y=9

3x+(-5x+9)=9

3x-5x+9=9

-2x+9=9

-9 -9

-2x=0

**x=0**

sub into y=-5x+9

y=-5(0)+9

**y=9**

On the graph it says it's 72 and 9 and another one is 144 and 18. Those are the two that I remember. So all you have to do is divide 72/9=8. 144/18=8 So the proportional relationship is 8. So the answer is **B) y=8x.**

Hope this helps! :)
